NOTES:a. She is believed to have been a niece of Duchess Gunnora, wife of Richard I, Duke of Normandy, perhaps daughter of Senfria.b. He was witness to a charter, 1031 or 1032, of Robert I, Duke of Normandy. Betwen 1028 and 1035, he restored to the abbey of Jumieges a market at Vimoutiers, near Montgomerie, of which he had deprived the monks. During the troubles of Duke William's minority, he was exiled to Paris on account of the murder of Osbern by his son William de Montgomery (who was later slain in revenge).c. In 1048 he was with Duke William on his expedition to Alencon and Domfront, and with William Fitz Osbern, was considered to be in the Duke's confidence. He was in the Duke's entourage on numerous occasions beginning in 1053, and he and his wife Mabel were high in the Duke's favor in 1061. Between 1050 and 1059 he founded the abbey of St. Martin de Troarn, and around 1055 he refounded the abbey of St. Martin at Sees. He was with the Duke in 1066 during the preparations for the invasion of England, but did not accompany him, instead remaining in Normandy to assist the Duchess in the government of the duchy. In 1067, he accompanied the new King to Engand whereupon he recieved a grant of Arundel and Chichester, and in 1074 he was created Earl of Shrewsbury. Between 1079 and 1080, he assisted in bringing about a peace between William and Fulk, Count of Anjou, and with other magnates also assisted in bringing a reconciliation between William and his son Robert. During the rebellion of 1088, he appears to have sympathized with Robert Curthose, regarding him as the rightful heir to the throne. While it is not clear to what extent he sided with the rebels, three of his sons, one being Robert de Belleme, were among those who held Rochester for Robert Curthose against the royal forces that summer. Later that year, Roger crossed over to Normandy and levied war against Duke Robert, who had imprisoned his son, Robert de Belleme, but ultimately a treaty was made and Robert de Belleme was released. He refounded Wenlock as a Cluniac priory, and founded the Benedictine abbey of Shrewsbury, and the priory of St. Nicholas at Arundel, and was also a benefactor of St. Evroul, St. Stephen's at Caen, and Cluny. He died three days after becoming a Monk at Shrewsbury. By first wife, Mabel, he had sons Roger, who died young and s.p.; Robert de Belleme; Hugh de Mongomery; Roger the Poitevin; Philip; and Arnulf, as well as four daughters, Emma, abbess of Almeneches; Maud married to Robert, Count of Mortain and Earl of Cornwall; Mabel, wife of Hugh, lord of Chateauneuf-en-Thimerais; and Sibyl, wife of Robert Fitz Hamon. By his second wife, Adelaide, he left a son, Everard, who was chaplain both to William Rufus and Henry I.d. She was murdered at Bures Castle by one Hugh Bunel and his accomplices. Her son, Hugh de Montgomery who was at Bures Castle when she was murdered there, pursued them in vain, they having broken down the bridges behind them as they fled. The pursuit was further hindered by the winter floods.e. Roger the Poitevin was a considerable tenant-in-chief, particularly in Lancashire, and he was one of the rebels in 1088. In 1102 he was banished from England with his brother Earl Robert (de Belleme) and retired to Poitou. He founded the priory of Lancaster as a cell of St. Martin of Sees. He has erroneously been called Earl of Lancaster; his comital style is attributable to the comte of Marche held in right of his wife, Almodis, sister of Boso, Count of Marche in Poitou.f. In 1073 he served in the Conqueror's invasion of Maine, and was knighted by the King at the siege of Fresnay-le-Vicomte. Around 1077 he joined the party of Robert Curthose. Upon his mother's death in Dec 1079, and in her right succeeded in France as Lord of Belleme, and either then or at his father's second marriage, he succeeded to the Norman lordships of Alencon and Domfront. In Sep 1087, upon hearing of William's death, he then conspired with the Conqueror's half-brothers and other nobles to dethrone William II in favor of Robert Curthose. But he and the rebels were besieged in Rochester Castle and in Jun 1088, they were forced to surrender. Soon reconciled with the King, upon his return to Normandy he was arrested by Duke Robert and imprisoned, but his father soon obtained his release. In 1090, Robert supported the Duke against the Norman rebels who favored William Rufus. Upon his father's death in 1094, he succeeded to all of his possessions in Normandy, and with the death of his brother, Hugh, in 1098, he obtained Hugh's Earldom and lands in England and Wales from the King, and thus became Earl of Shrewsbury. He was in Normandy when William Rufus was killed, and hastened to England to do homage to Henry I, who confirmed him in all his lands and dignities. In Oct 1100, on the death of his father-in-law, he became Count of Ponthieu, and the following year, with other nobles, he urged Robert of Normandy to invade England. But as this was unsuccessful he fled and then devastated Staffordshire with a force of Normans and Welsh. The King then took his castles of Arundel, Blythe and Bridgnorth and besieged him at Shrewsbury, whereupon Robert finally surrendered and was given safe conduct to the sea. He was deprived of all of his honours and lands in England and Wales, including the Earldom, whence he retired to Normandy. In 1105 he was at war with Rotrou, Count of Perche, who had claimed a share of the great Belleme inheritance, and who defeated him, and in the autumn of 1105 he attacked Henry's supporters in Normandy. When Henry invaded Normandy in autumn of the following year, Robert adhered to the Duke, and commanded the rear division at Tinchebrai 28 Sep, but fled when the front division was devastated. Failing in his attempt to seduce the Count of Maine from his allegiance with Henry, Robert made peace with the King, and on 17 May 1110 he was with Henry at Dover. But the following year Robert took a leading part in the plot to restore Normandy to Duke Robert's son, William Clito, and in 1112 rebelled and aided the Count of Anjou against the King. When the King of France sent him as Ambassador to negotiate with Henry regarding the release of Duke Robert, the King seized him, tried, and then condemned him to imprisonment. He was at first confined at Cherbourg, but King Henry later took him to England where he was imprisoned at Wareham Castle in Dorset, where he presumably died some nineteen years later.g. Sole heir to her father's comte, she was reportedly cruelly treated by her husband, being kept shut up for a long period in his castle at Belleme. She eventually escaped and took refuge with Adela, Countess of Blois, and retired to Ponthieu, never returning to her husband.h. He succeeded his father as Count of Ponthieu, probably between 1105/06 and 1110/1111. In Jun 1119, Henry I restored to him all of his father's lands in Normandy. He resigned Ponthieu to his son Guy in or after 1126, but retained the title of Count of Ponthieu. In 1135, Henry I confiscated his Norman lands, whereupon he joined Geoffrey Plantagenet, with whom he invaded Normandy after the death of Henry I.
